Freak wave kinematics in unidirectional deep water waves
- Gifu Univ. (Japan)
This study aims to clarify the kinematics of freak waves caused by the high-order nonlinear interaction of deep water waves on a two-dimensional domain. The hydrodynamic equations for an irrotational flow are solved by using a high-order spectral method and then their numerical solutions are used to investigate the characteristics of surface profiles and internal velocity field of the freak waves. As a result, it is found that the kinematics of the freak waves occurring in a deep water wave train are strongly influenced by the water surface profile above MWL and the bound modes due to the higher harmonics and hence their modeling requires the evaluation of the form of freak wave crest and high-order nonlinear interactions more than the 3rd order.
